Abstract
The utility model discloses an auxiliary air intake system of a slurry bed reactor gas distributor. The auxiliary air intake system of the slurry bed reactor gas distributor comprises a slurry bed reactor, a catalyst discharge buffer tank, a recycle gas automatic compressor and a steam heater, wherein a synthesis gas inlet and a recycle gas inlet are arranged on the catalyst discharge buffer tank; the air inlet and the air outlet of the steam heater are connected with the synthesis gas inlet of the catalyst discharge buffer tank through a pipeline; and an air outlet of the recycle gas automatic compressor is connected with the recycle gas air inlet of the catalyst discharge buffer tank through the pipeline. The auxiliary air intake system has the advantages that the blocked gas distributor resistance is greatly reduced; the potential safety hazards of the compressor and a pre-system are eliminated; the air intake quantity is increased; the production load is further improved; the economic benefit is further improved; the repair cycle of the slurry bed reactor is prolonged; the safety risk in the overhaul process is reduced; a lot of time is made for production; and the production efficiency is also improved.
Description
Technical field
The utility model relates to a kind of gas handling system, particularly relates to a kind of additional-air inlet system of paste state bed reactor gas distributor.
Background technology
Paste state bed reactor comprises following four parts at least: the inlet gas distributor, heat exchanging pipe, gas-liquid separate component, outlet dedusting foam removal parts, so paste state bed reactor is compared with other reactors, have bed temperature evenly, catalyst transmits that resistance is little, back-mixing large, the conversion ratio advantages of higher.The plant issue and the technological problems that come due to its structure member multi-band on the contrary also emerge in an endless stream.As: can't change online after gas distributor, gas-liquid separation device break down, the problems such as processing need to stop.
Because the hybrid power of paste state bed reactor is process gas, in case power failure or other reasons cause source of the gas power to disappear, slurries just can flow backward to gas distributor inside, and the slurries that enter gas distributor are difficult to again be blown with catalyst, thereby cause gas distributor to stop up.Have following problem after gas distributor stops up: after (1) gas distributor is poured slurries into, very difficult Hand scarf is gone out, severe patient needs the parking maintenance cleaning, have very large risk factors in long and maintenance process of the cycle of parking maintenance, stopping, it is also larger to process the catalyst activity impact; (2) after distributor stops up, resistance increases, and causes the increase of recycle gas compressor load, electric current to raise, and there is hidden trouble of equipment in the long-term operation of motor; (3) after gas distributor stops up, resistance increases, and causes the pressure of front system gasification furnace to raise, and has security risk; (4) increase of gas distributor resistance causes process gas can't enter slurry attitude bed, produces load and is difficult to raising.
The utility model content
The purpose of this utility model is the additional-air inlet system of the paste state bed reactor gas distributor that but a kind of extension device repair time is provided, enhances productivity.
the purpose of this utility model is implemented by following technical scheme, a kind of additional-air inlet system of paste state bed reactor gas distributor, it comprises paste state bed reactor, catalyst discharging surge tank, circulating air is from compressor and steam heater, the bottom of described paste state bed reactor is provided with gas distributor, the bottom of described gas distributor is provided with the reactor bottom discharge port, the middle part of described paste state bed reactor is provided with the catalyst discharge port, described catalyst discharge port all is connected with the charging aperture pipeline of described catalyst discharging surge tank with described reactor bottom discharge port, the gas outlet of described steam heater is connected with the air inlet duct of described gas distributor, described catalyst discharging surge tank is provided with synthesis gas air inlet and circulating air air inlet, the air inlet place of described steam heater all is connected by the synthesis gas air inlet of pipeline with described catalyst discharging surge tank with the place, gas outlet, described circulating air is connected with the circulating air air inlet duct of described catalyst discharging surge tank from the gas outlet of compressor.
synthesis gas major part in steam heater enters gas distributor through pipeline by the air inlet of gas distributor, another fraction gas is entered in catalyst discharging surge tank by the pipeline of steam heater air inlet end and gas outlet end, circulating air is squeezed into recyclegas in catalyst discharging surge tank by the circulating air air inlet of catalyst discharging surge tank from compressor, a gas part in catalyst discharging surge tank is unloaded stockline through reactor bottom and is entered in paste state bed reactor by the reactor bottom discharge port, another part is entered in paste state bed reactor by the catalyst discharge port through catalyst discharging bus, two-way gas enters in paste state bed reactor, the deficiency that is used for make-up gas distributor air inflow.
The utility model has the advantage of, (1) greatly reduces and stops up rear gas distributor resistance by increasing the additional-air inlet system of gas distributor, eliminates compressor and front security of system hidden danger; (2) after gas distributor stopped up, deficiency of air after increasing the additional-air inlet system, increased air inflow, further improves and produces load, and economic benefit is further enhanced; (3) use the utility model system after, extend the paste state bed reactor time between overhauls(TBO), reduce the security risk in maintenance process, strive for the plenty of time for production, improved production efficiency.
